             Summary: [C++] Segfault in arrow-compute-plan-test 
ExecPlanExecution.SourceScalarAggSink
                 Key: ARROW-13341
                 URL: https://issues.apache.org/jira/browse/ARROW-13341
             Project: Apache Arrow
          Issue Type: Bug
          Components: C++
            Reporter: David Li


https://github.com/apache/arrow/pull/10608/checks?check_run_id=3068468137
On "AMD64 MacOS 10.15 C++"

Looks like a state wasn't initialized somehow?
